TL;DR: The NCEP/NCAR 40-yr reanalysis uses a frozen state-of-the-art global data assimilation system and a database as complete as possible, except that the horizontal resolution is T62 (about 210 km) as discussed by the authors.

TL;DR: The National Centers for Environmental Prediction (NCEP) and National Center for Atmospheric Research (NCAR) have cooperated in a project to produce a retroactive record of more than 50 years of global analyses of atmospheric fields in support of the needs of the research and climate monitoring communities as mentioned in this paper.

TL;DR: The Climate Forecast System (CFS) as discussed by the authors is a fully coupled ocean-land-atmosphere dynamical seasonal prediction system, which became operational at NCEP in August 2004.

TL;DR: In this article, an extension of the Eliassen-palm flux concept to the time-averaged three space dimension problem is presented. But the authors focus on the behavior of the large-scale eddies themselves, not only the shape and propagation of the eddies, but also their feedback on the mean flow.

TL;DR: A number of improvements were implemented on 6 March 1991 into the National Meteorological Center's global model, which is used in the global data assimilation system (GDAS), the aviation (AVN) forecast, and the medium-range forecast (MRF): the horizontal resolution of the forecast model was increased from triangular truncation T80 to T126, which corresponds to an equivalent increase in grid resolution from 160 km to 105 km.
